PURPOSE: To allow to branch wire communication cables from two directions simply and at a low cost, by providing the first and the second bent pipes whose pipe ends are directed in the direction orthogonal to the axis of a main pipe, to the first and the second branch pipes branching at an acute angle to the axis of the main pipe. CONSTITUTION: A branch pipe coupling 10 to distributing wire a communication cable to connect a CATV, a cable broadcasting, and the like, and customers 12, and a communication cable to connect customers each other, from a main pipe, is composed by connecting the first and the second bent pipes 20a and 20b to a coupling main body 18. In the coupling main body 18, the first and the second branches 24a and 24b branching at an acute angle to the axis of the main pipe are provided integrally extending in the directions opposing each other, on the outer surface of a saddle 22. And the bent pipes 20a and 20b have a bending property, and have bellows form of bent pipes 28a and 28b which are bent at a curvature radius of a tolerable bending radius or more than the tolerable bending radius. At both ends of the bent pipes 28a and 28b, sockets 30a and 30b, and spigots 32a and 32b, are formed respectively.
